DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024]FIG. 1 is a diagram illustrating an embodiment of the contents data managing system according to the present invention. A persona computer 1 is connected to a network 2 comprising a Local Area Network, the Internet, or the like. The personal computer 1 takes music data received from an EMD (Electrical Music Distribution) server 3 or read from a CD (Compact Disk) (such music data will hereafter be referred to as “contents”) and either records the contents as such, or converts the contents into a predetermined encoded format (e.g., ATRAC3 (Registered Trademark)) and also encrypts the contents with an encrypting format such as DES (Data Encryption Standard) and then records the contents.

[0025] The personal computer 1 records rights information indicating usage conditions of the contents, corresponding to the contents recorded in plaintext or as enciphered data.

[0026] The rights information indicates, for example, the number of portable devices (hereafter also referred to as simply “PD”) which can simultaneously use the contents corresponding to the rights information (the number of PDs which can check-out, as described later). Even in the event that there has been check-out of the contents to the number of times indicated in the rights information, the personal computer 1 is capable of playing the contents.

[0027] Also, the rights information indicates that the contents can be copied. In the event that the contents are copied to the portable devices 5-1 through 5-3, the personal computer 1 is still capable of playing the contents recorded therein. The number of times that the contents can be recorded to the portable devices 5-1 through 5-3 may be restricted. In this case, the number of times that copies can be made never increases.

[0028] Also, the rights information indicates whether the contents can be moved to another personal computer, and so forth. After the contents are moved to the portable devices 5-1 through 5-3, the contents recorded in the personal computer 1 cannot be used any more (either the contents are deleted, or the rights information is changed so that the contents are no longer usable).

[0029] Or, the rights information indicates that, following moving the contents from a recording medium to the personal computer 1, only check-out or check-in is permitted (so-called importing). Contents imported from memory cards 9-1 through 9-4 to the personal computer 1 are permitted to be, for example, checked-out to the portable devices 5-1 through 5-3, but moving the contents to another personal computer or the memory cards 9-1 through 9-4 is not permitted.

[0030] Details of rights information will be described later.

[0031] The personal computer 1 stores the contents which are recorded in an encrypted state along with the data relating to the contents (i.e., music piece title, playing conditions, etc.) to the portable device 5-1 that is connected thereto via a USB (Universal Serial Bus) cable, and also updates the rights information corresponding to the stored contents in accordance with the storing of the contents in the portable device 5-1 (hereafter referred to as “check-out”). More specifically, in the event of check-out, the number of times that check-out can be performed in the rights information corresponding to the contents recorded in the personal computer 1 is decremented by 1. When the number of times that check-out can be made reaches zero, the corresponding contents cannot be checked-out.

[0032] The personal computer 1 stores the contents which are recorded in an encrypted state along with the data relating to the contents to the portable device 5-2 that is connected thereto via a USB cable, and also updates the rights information corresponding to the stored contents in accordance with the storing of the contents in the portable device 5-2. The personal computer 1 stores the contents which are recorded in an encrypted state along with the data relating to the contents to the portable device 5-3 that is connected thereto via a USB cable, and also updates the rights information corresponding to the stored contents in accordance with the storing of the contents in the portable device 5-3.

[0033] Also, the personal computer 1 causes the portable device 5-1 connected thereto via a USB cable to delete (or render unusable) the contents which the personal computer 1 has checked-out to the portable device 5-1, and updates the rights information corresponding to the deleted contents (hereafter referred to as “check-in”). More specifically, at the time of check-in, the number of times that check-out can be performed in the rights information corresponding to the contents recorded in the personal computer 1 is incremented by 1.

[0034] The personal computer 1 causes the portable device 5-2 connected thereto via a USB cable to delete (or render unusable) the contents which the personal computer 1 has checked-out to the portable device 5-2, and updates the rights information corresponding to the deleted contents. The personal computer 1 causes the portable device 5-3 connected thereto via a USB cable to delete (or render unusable) the contents which the personal computer 1 has checked-out to the portable device 5-3, and updates the rights information corresponding to the deleted contents.

[0035] The personal computer 1 cannot check-in contents checked-out to the portable device 5-1 by another personal computer not shown in the drawings. The personal computer 1 cannot check-in contents checked-out to the portable device 5-2 by another personal computer. The personal computer 1 cannot check-in contents checked-out to the portable device 5-3 by another personal computer.

[0036] In response to a request from the personal computer 1, the EMD server 3 supplies contents to the personal computer along with data relating to the contents (e.g., music piece title, playing restrictions, etc.), via the network 2.

[0037] The contents which the EMD server 3 supplies are encoded by a predetermined encoding method, and encrypted with a predetermined encryption method. The EMD server 3 supplies a key for deciphering the contents to the personal computer 1.

[0038] In response to a request of the personal computer 1, a WWW (World Wide Web) server 4 supplies data corresponding to a CD from which contents are read (e.g., CD album title, CD record company, etc.) and data corresponding to the contents read from a CD (e.g., music piece title, name of composer, etc.), to the personal computer 1.

[0039] The portable device 5-1 stores the contents supplied from the personal computer 1 (i.e., check-out contents, etc.) along with data relating to contents (e.g., music piece title, rights information, etc.). The portable device 5-1 plays the stored contents based on the data relating to the contents, and outputs the contents to an unshown headphone set or the like.

[0040] For example, in the event that a user attempts to play contents a number of times exceeding the number of playing times described in the rights information stored as data relating to the contents, the portable device 5-1 stops playing of the corresponding contents. In the event that a user attempts to play contents after expiration of the playing period described in the rights information stored as data relating to the contents, the portable device 5-1 stops playing of the corresponding contents.

[0041] The user can remove the portable device 5-1 storing the contents from the personal computer 1 carry the portable device 5-1, and further play the contents stored therein so that music or the like corresponding to the contents can be listened to through the headphones or the like.

[0042] The portable device 5-2 stores the contents supplied from the personal computer 1 along with data relating to contents. The portable device 5-2 plays the stored contents based on the data relating to the contents, and outputs the contents to an unshown headphone set or the like. The user can remove the portable device 5-2 storing the contents from the personal computer 1 carry the portable device 5-2, and further play the contents stored therein so that music or the like corresponding to the contents can be listened to through the headphones or the like.

[0043] The portable device 5-3 stores the contents supplied from the personal computer 1 along with data relating to contents. The portable device 5-3 plays the stored contents based on the data relating to the contents, and outputs the contents to an unshown headphone set or the like. The user can remove the portable device 5-3 storing the contents from the personal computer 1 carry the portable device 5-3, and further play the contents stored therein so that music or the like corresponding to the contents can be listened to through the headphones or the like.

[0044] The memory card 9-1 is inserted into a terminal device 6 installed at a shop or the like, and contents which the user has purchased by operating the terminal device 6 are stored therein along with corresponding rights information. The predetermined contents stored in the memory card 9-1 are permitted to be imported based on the rights information, and moving thereof is not permitted.

[0045] The memory card 9-1 storing the contents is mounted in a slot in the personal computer 1. The personal computer 1 imports the contents stored in the memory card 9-1 mounted thereto. The personal computer 1 generates rights information permitting only check-in or check-out corresponding to the imported contents, and stores the generated rights information. The contents imported to the personal computer 1 are permitted for check-out to the portable devices 5-1 through 5-3, or permitted for check-in from the portable devices 5-1 through 5-3, based on the rights information.

[0046] The memory card 9-2 is inserted into a cellular telephone 7, and contents which the user has purchased by operating the cellular telephone 7 (e.g., contents downloaded via a cellular telephone line) are stored therein along with corresponding rights information. The predetermined contents stored in the memory card 9-2 are permitted to be imported based on the rights information, and moving thereof is not permitted.

[0082] Upon a request from the GUI unit 101 to move contents from the memory card 9 to the personal computer 1, the transfer processing unit 103 supplies the media contents ID corresponding to the contents regarding which moving has been requested to the memory card plug-in 112, as well as requesting moving of the contents corresponding to the media contents ID. The transfer processing unit 103 obtains the contents to be moved from the memory card plug-in 112 along with the corresponding rights information.

[0083] The transfer processing unit 103 supplies the moved contents to the music piece managing unit 104 along with the rights information.

[0084] At the time of transferring contents to the portable device 5-1, the PD plug-in 111-1 performs mutual verification with the portable device 5-1. In the event that the mutual verification fails, the PD plug-in 111-1 does not transfer contents to the portable device 5-1.

[0085] At the time that contents are supplied from the transfer processing unit 103, in the event that the contents are encrypted, the PD plug-in 111-1 supplies the contents along with the data relating to the contents to the portable device 5-1. Upon the contents being supplied from the transfer processing unit 103, in the event that the contents are not encrypted, the PD plug-in 111-1 encrypts the contents, and supplies the encrypted contents along with the data relating to the contents to the portable device 5-1.

[0086] Incidentally, the processing for mutual verification may be executed at the point that the portable device 5-1 is connected to the personal computer 1.

[0087] At the time of transferring contents to the portable device 5-2, the PD plug-in 111-2 performs mutual verification with the portable device 5-2. In the event that the mutual verification fails, the PD plug-in 111-2 does not transfer contents to the portable device 5-2.

[0088] At the time that contents are supplied from the transfer processing unit 103, in the event that the contents are encrypted, the PD plug-in 111-2 supplies the contents along with the data relating to the contents to the portable device 5-2. Upon the contents being supplied from the transfer processing unit 103, in the event that the contents are not encrypted, the PD plug-in 111-2 encrypts the contents, and supplies the encrypted contents along with the data relating to the contents to the portable device 5-2.

[0089] Incidentally, the processing for mutual verification may be executed at the point that the portable device 5-2 is connected to the personal computer 1.

[0090] The user can further additionally install PD plug-ins to the personal computer 1.

[0091] In the following description, the PD plug-ins 111-1 and 111-2 will be referred to simply as PD plug-in 111, unless there is the need to distinguish between the individual PD plug-ins 111-1 or 111-2.

[0092] Upon a contents import request from the transfer processing unit 103, the memory card plug-in 112 reads the contents corresponding to the media contents ID from the memory card 9, along with the corresponding rights information. The memory card plug-in 112 supplies the read contents to the transfer processing unit 103 along with the rights information.

[0093] Upon a request from the transfer processing unit 103 to move contents, the memory card plug-in 112 reads the contents corresponding to the media contents ID out from the memory card 9, along with the corresponding rights information. The memory card plug-in 112 supplies the contents read out and the rights information to the transfer processing unit 103.

[0094] The music piece managing unit 104 records data in the database 107, such as the music piece title, file name corresponding to the contents, etc., and reads out the music piece title, file name, etc., from the database 107. Upon receiving the music piece title or file name from the GUI unit 101, the music piece managing unit 104 adds a record to the database 107, and records the music piece title or file name as a record item.

[0095] Upon being supplied with the contents to be imported and the rights information from the transfer processing unit 103, the music piece managing unit 104 records data such as the music piece title, file name corresponding to the contents, etc., and also records the contents in the music piece file storing unit 108-1 or 108-2. The music piece managing unit 104 generates new rights information based on the rights information supplied corresponding to the imported contents, and records the newly-generated rights information in the rights information storing unit 105. At this time, the rights information generated at the music piece managing unit 104 makes record to the effect that only check-in or check-out is permitted.

[0130] Description will be made regarding the icons corresponding to the rights information which are displayed on the display 20 by the GUI unit 101, with reference to the example shown in FIGS. 8 and 9.

[0131] The GUI unit 101 displays on the display 20 a window containing a field 201 for displaying music piece titles and the like corresponding to the contents stored in the memory card 9.

[0132] In the event that the copy control flag corresponding to the contents stored in the memory card 9 is “1”, and the equipment ID corresponding to the contents stored in the memory card 9 is the same as the equipment ID of the personal computer 1, this means that check-in is permitted for the contents, so the GUI unit 101 displays in the field 201 an icon 202-1 or 202-2 (e.g., an eighth note icon) indicating that check-in is permitted, in a manner corresponding to the music piece title or the like of the contents.

[0133]FIG. 9A is a drawing illustrating the icon 202-1 or 202-2. In the following description, the icons 202-1 and 202-2 will be referred to simply as icon 202, unless there is the need to distinguish between the individual icons 202-1 and 202-2.

[0134] In the event that the copy control flag corresponding to the contents stored in the memory card 9 is “3”, this means that importing is permitted for the contents, so the GUI unit 101 displays in the field 201 an icon 203 (e.g., a bass clef icon) indicating that importing is permitted, in a manner corresponding to the music piece title or the like of the contents.

[0135]FIG. 9B is a drawing illustrating the icon 203.

[0136] In the event that the copy control flag corresponding to the contents stored in the memory card 9 is “1”, and the equipment ID corresponding to the contents stored in the memory card 9 is not the same as the equipment ID of the personal computer 1, this means that check-in is not permitted for the contents, so the GUI unit 101 displays in the field 201 an icon 204 (e.g., a quarter rest icon) indicating that check-in is not permitted, in a manner corresponding to the music piece title or the like of the contents.

[0137]FIG. 9C is a drawing illustrating the icon 204.

[0138] In the event that the copy control flag corresponding to the contents stored in the memory card 9 is “2”, this means that moving is permitted for the contents, so the GUI unit 101 displays in the field 201 an icon 205 (e.g., a sharp icon) indicating that moving is permitted, in a manner corresponding to the music piece title or the like of the contents.

[0139]FIG. 9D is a drawing illustrating the icon 205.

[0140] In the event that contents regarding which importing are selected, i.e., in the event that contents with the icon 203 are selected and the button 206 is clicked, the GUI unit 101 makes a request to the transfer processing unit 103 to import corresponding contents.

[0141] Next, the processing for displaying icons with the GUI unit 101 will be described with reference to the flowchart shown in FIG. 10.

[0142] In step S11, the GUI unit 101 judges whether or not the copy control flag contained in the rights information read out from the memory card 9 via the memory card plug-in 112 and the transfer processing unit 103 indicates permission to import, and in the event that judgment is made that the copy control flag indicates permission to import, the flow proceeds to step S12, the icon 203 indicating permission to import is set, and the flow proceeds to step S20.

[0143] In step S11, in the event that the GUI unit 101 judges that the copy control flag does not indicate permission to import, the flow proceeds to step S13, wherein the GUI unit 101 judges whether or not the copy control flag contained in the rights information indicates permission to move, and in the event that judgment is made that the copy control flag indicates permission to move, the flow proceeds to step S14, the icon 205 indicating permission to move is set, and the flow proceeds to step S20.

[0144] In step S13, in the event that the GUI unit 101 judges that the copy control flag does not indicate permission to move, the flow proceeds to step S15, wherein the GUI unit 101 judges whether or not the copy control flag contained in the rights information indicates checked-out contents, and in the event that judgment is made that the copy control flag indicates checked-out contents, the flow proceeds to step S16.

[0145] In step S16, the GUI unit 101 judges whether or not the equipment ID contained in the rights information is the same as its own equipment ID, and in the event that judgment is made that the equipment ID contained in the rights information is the same as its own equipment ID, the flow proceeds to step S17, an icon indicating own check-out, i.e., the icon 202 indicating permission to check-in is set, and the flow proceeds to step S20.

[0146] In the event that judgment is made in step S16 that the equipment ID contained in the rights information is not the same as its own equipment ID, the flow proceeds to step S18, an icon indicating check-out from other equipment, i.e., the GUI unit 101 sets the icon 204 indicating that check-in is not permitted, and the flow proceeds to step S20.

[0147] In step S15, in the event that the GUI unit 101 judges that the copy control flag does not indicate checked-out contents, the flow proceeds to step S19, a default icon (an icon other than any of the icons 202, 203, 204, or 205) is set, and the flow proceeds to step S20.

[0148] In step S20, the GUI unit 101 displays the set icon, and the processing ends.

[0149] Thus, the GUI unit 101 displays icons corresponding to the copy control flag contained in the rights information read out from the memory card 9, the user can speedily know operations which are permitted regarding the contents.

[0150] Now, while the contents have been described as being music data, the contents may be data such as moving images, still images, numerical values, or may be programs or the like.
